摘要: The interaction of elemental mercury with defective carbonaceous clusters is investigated by the density-functional theory calculation. cluster represented seven-fused benzene ring and single atomic vacancy at surface. Also, non-defective surface employed for comparison. chlorine carried out to evaluate effect statured carbon neighboring sites on adsorption. results indicate that can promote activity its sites, has much larger adsorption energy than without chlorine. Cl atom improve surface, but very complex, which depends concentration. High concentration decreases because competes active mercury. Hence, we find be regarded as a potential functional group saturated rapidly decrease capture capacity.
